Abstract:V komunalni odpadni vodi je vedno večja prisotnost mikroplastike. Ta se med čiščenjem koncentrira na čistilni napravi, kar nalaga komunalnim čistilnim napravam veliko odgovornost koliko mikroplastike se izpusti nazaj v okolje in koliko se je zadrži ter kar se z zdržano mikroplastiko zgodi. V diplomskem delu smo s pomočjo postopkov filtracije, kemijske oksidacije, usedanja in dekantiranja izolirali mikroplastiko iz vodnih vzorcev ter vzorcev blata. Delce mikroplastike smo preučili pod optičnim mikroskopom ter jih karakterizirali z infrardečo spektroskopijo. S pomočjo infrardeče spektroskopije smo določili prisotnost značilnih funkcionalnih skupin v vzorcu mikroplastike, posnete spektre smo primerjali z referenčnimi spektri različnih polimernih materialov z znano strukturo. Določili smo tudi mase trdnih snovi po dveh filtracijah vzorcev vode in blata, ter določili uspešnost kemijske oksidacije organskih snovi.

Title:Comparison of microplastics content in wastewater and sludge at wastewater treatment plants
Abstract:There is a growing presence of microplastics in municipal wastewater. During the cleaning process, it concentrates at the sewage treatment plant, which imposes a great responsibility on municipal sewage treatment plants on how much microplastics is released back into the environment and how much is retained and what happens with the lasting microplastics. In the Bachelor's degree, we islated microplastics from aqueous and sludge samples by filtration, chemical oxidation, deposition and decantation processes. Microplastics particles were examined under an optical microscope then we recorded infrared spectres, which were the basis for chemical identification. The presence of typical functional groups in the microplastic samples were determined by infrared spectroscopy. Recorded spectra were compared with the reference spectra of various polymeric materials with known structure. We also determined the masses of solids after two filtrations of water and sludge samples, and determined the success of chemical oxidation of organic matter.
